Ultimate Fighting Championship will return to London's O2 Arena on Saturday, 16 March.
It will be the 11th time a UFC event has been held in the capital, including Britain's Michael Bisping's victory over Anderson Silva in 2016.
No fighters or line-ups have been announced yet for next year's date.
UFC light heavyweight and Londoner Jimi Manuwa says it would be a "dream" to compete in his home city, adding: "There's nothing like the London fans."
Fellow British UFC welterweight Danny Roberts, added: "I have had some of my best career highlights in London, and I know that every time I perform there, I will be adding another one to the list.
"MMA fans are some of the best sporting fans in the world, and London is that one city that I know they will show me that."
